An approximation of absolute zero was made from an extrapolation of

A) P vs. 1/V
B) V vs. T
C) n vs. V
D) V vs. 1/T

Question 2

Calculate the bond energy of CF given that the heat of atomization of CHFClBr is 1502 kJ/mol, and that the bond energies of CH, CBr, and CCl are 413, 276, and 328 kJ/mol, respectively.

What will be an ideal response?

Answer to Question 1

B

Answer to Question 2

Hatomiztion = D(CH) + D(CF) + D(CCl) + D(CBr)
D(CF) = Hatomiztion - D(CH) + D(CCl) + D(CBr)
= 1502 - (413 + 276 + 328) kJ/mol
= 485 kJ/mol
